MEANS FOR SUPPLYING LUBRlCATlNG-OIL T0 MOVING PARTS OF ENGINES.

SPECIFICATION forming part of .Letters Patent No. 446,797, datedFebruary 17, 1891.

Application filed September 1,1890. Serial No. 363,727- (No model.)

To all whom it may concern:

Be it known that 1, DAVID R. STILES, a citi zen of the United States,and a resident of Ottawa, in the county of Franklin and State of Kansas,have invented certain new and useful Improvements in Means for SupplyingLubricating-Oils to the Moving Parts of Engines; and I do hereby declarethat the following is a full, clear, and exact description of theinvention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

My invention relates to improvements in means for supplyinglubricating-oil to moving parts of engines, and is designed,principally, for oiling the wrist-pins of driving-cranks.

The object of the invention is to provide simple, economical, andefiicient means for accomplishing the above purpose.

The invention consists, essentially, in an oilreservoir located abovethe crank, having an opening or hole in the bottom, through which theoil escapesin drops, and a conveying device carried by the pitmanconnected with the crank, said device being provided with knives andhaving. an oil-passage, so that at each revolution of the crank the saidknives will take the oil from the oil-receptacle and convey it to thewrist-pin, as will hereinafter be more fully described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of aportion of a steamengine, showing my improvements applied thereto. Fi 2is a vertical section of the conveying tube or pipe and oil-receptacle.Fig. 3 is a plan view of the conveying-tube. Fig. 4 is a front view.Fig. 5 is a plan view of the knives detached.

In the said drawings, the reference-numeral 1 designates theoil-receptacle, consisting of a curved metallic bar having an oil-cup 2and provided with an oil-passage 3 and escapeopening 4. Thisoil-receptacle may be secured to the engine at any convenient point, andis so located with respect to the crank that the opening l will be inthe vertical plane thereof.

The numeral 5 designates the crank, 6 the wrist-pin, and 7 the pitmanconnected with said wristpin and with the piston-rod of the engine.

'7 designates the conveying device, consist- 10 designates anoil-passage communicating with the groove 8. This passage for part ofits length is made zigzag and vertical for the remaining portion, asseen in Fig. 2.

The nu mera1s12 and 13 designate oil-collecting knives fitting in thegrooves in the flanges 8. These knives are curved or rounded and theshank lat of the lower knife fitting in the groove 9, but not closingthe oil opening or passage 10. A space 15 is thus formed between thebeveled face of the tube and the said knife for the passage of the oilcollected by the knife. The knife 13 is located above the lower knife,with a small space therebetween, and does not extend upwardly quite sofar as knife 12.

The operation is as follows: The oil-receptacle is properly adjusted, sothat the knife 12 of the conveying-tube will just touch the same at thepoint where the oil-opening 4 is, the said receptacle being curved, asseen in Fig. 1, for that purpose. The oil-cup and oilreceptacle are soconstructed and arranged as to feed the oil to the escape-opening 4:drop by drop, and at each revolution of the crank the knife 12 willdetach a drop of oil, which will pass down the space between the saidknife and the beveled end of the tube to the oil-passage 10, from whenceit will be fed to the wrist-pin. The upper knife 13 will pass the dropof oil on the receptacle without touching it, and is merely intended togather the oil which may draw over from knife 12when feeding very heavyfrom said latter knife.

The invention is applicable for oiling or lubricating eccentrics andother moving parts of an engine as well as wrist-pins, and therefore Ido not confine myself to such use.

It is obvious that the oil-receptacle, instead of being hollow andprovided with an escapeopening, may consist of a solid curved bar.

In such case the oil would flow down the urn der side thereof andcollect at the point where the knife touches, and the same would begathered therebyand ted to the wrist-pins.

From the above it will be Seen that the oil is positively supplied tothe wrist-pin at each revolution of the crank, and the receptacle, beingstationary and not connected with the moving parts of the engine, can bereadily supplied with oil without stopping the engine.

The object of beveling the upper end of tube 7* is to allow the oil toHow readily to the passage 10,and the latter is made zigzag, so that theoil will not be forced out by the movement of the part to which saidtube is attached.

Having thus described my invention, what I claim is- 1. The combination,with a stationary oilreceptacle, of a eonveyingdube carried by a movingpart of an engine, said tube being provided with a gathering-knife and azigzag oil-passage communicating with the part to be lubricated,substantially as described.

2. The combination, with a stationary oilreceptacle, of a conveying-tubecarried bya knife located in said grooved flange, substantially asdescribed.

3. The combination, with a stationary oilreceptacle, of a conveying-tubehaving a beveled end carried by a moving part of an engine, said tubehaving upwardly-projecting grooved flanges, a groove closed at its lowerend, an oil-passage communicating with said. groove, a gathering-knifelocated in said grooved flanges, and a supplemental knife 10- catcdabove said first-mentioned knife, substantially as described.

4. The combination, with a stationary oilrcceptacle having an oilcup, anoil-passage, and an escape-opening, of a conveying-tube carried by amoving part of an engine, said tube having upwardly-projecting groovedflanges, a groove closed at one end, an oilpassage communicating withsaid groove, a gatheringknife located in said grooved flanges, and asupplemental knife located above the first-mentioned knife,substantially as described.

In testimony that I claim the foregoing as my own I have hereuntoat'fixed mysignaturc in presence of two witnesses.

DAVID R. STILES.
